BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens triplinervia and hereinafter referred to by the name ‘Haflpare’.

The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Okayama-ken, Japan. The objective of the breeding program is to create new freely-branching Bidens plants with unique ray floret coloration.

The new Bidens plant originated from a self-pollination made by the Inventor in Okayama-ken, Japan in January, 2010 of Bidens triplinervia ‘K-SAIKA001’, not patented. The new Bidens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Okayama-ken, Japan in May, 2010.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Okayama-ken, Japan since June, 2010 has shown that the unique features of this new Bidens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Bidens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Haflpare’. These characteristics in combination distinguish ‘Haflpare’ as a new and distinct Bidens plant:

-   -   1. Upright, outwardly spreading to somewhat trailing and         mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Long flowering period.     -   6. Inflorescences with deep orange and yellow bi-colored ray         florets and bright yellow-colored disc florets.     -   7. Strong peduncles that hold the inflorescences above and         beyond the foliar plane.

Plants of the new Bidens differ primarily from plants of the parent, ‘K-SAIKA001’ in ray floret color as inflorescences of ‘K-SAIKA001’ have yellow and subdued orange bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Haflrest’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed from plants of ‘Hafltibr’ in ray floret color as plants of ‘Haflrest’ have dark orange-colored ray florets with yellow-colored borders.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltibr’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed from plants of ‘Hafltibr’ in plant size and ray floret color as plants of ‘Hafltibr’ are more compact than plants of the new Bidens and have orange-colored ray florets with orange red-colored central and lateral stripes.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltifrpu’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed from plants of ‘Hafltifrpu’ in plant size and ray floret color as plants of ‘Hafltifrpu’ are more compact than plants of the new Bidens and have orange and yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltufr’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed from plants of ‘Hafltufr’ in ray floret color as plants of ‘Hafltufr’ have ray florets with dark orange-colored centers and yellow to light yellow-colored apices.

Plants of the new Bidens can also be compared to plants of Bidens triplinervia ‘Florbikanre’, disclosed in U.S. Plant Pat. No. 24,867. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed from plants of ‘Florbikanre’ in the following characteristics:

-   -   1. Plants of the new Bidens were taller than plants of         ‘Florbikanre’.     -   2. Plants of the new Bidens had longer and thicker lateral         branches than plants of ‘Florbikanre’.     -   3. Plants of the new Bidens had shorter leaves than plants of         ‘Florbikanre’.     -   4. Plants of the new Bidens and ‘Florbikanre’ differed in ray         floret color as plants of ‘Florbikanre’ had light red-colored         ray florets.     -   5. Plants of the new Bidens had shorter peduncles than plants of         ‘Florbikanre’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Bidens plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Bidens plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Haflpare’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 15-cm containers during December in a polyethylene-covered greenhouse in Cartago, Costa Rica and under cultural practices which approximate those generally used in commercial Bidens production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 18° C. and light levels ranged from 12 to 15 moles per day. Plants were pinched two times and were 21 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
